feat: zone entry toast and unspent talent points indicator

- Zone entry toast: centered slide-down banner when entering a new
  zone (tracks renderer's zone name, fires on change)
- Talent indicator: pulsing green '! N Talent Points Available' below
  minimap alongside existing New Mail / BG queue indicators
